The Tajweed color system in Tarteel highlights Madd (prolongation), Ghunna, Qalqalah, Tafkhim, and Silent letters.

Dark Red — Necessary Prolongation (Madd Laazim)

The dark red color indicates letters that must be elongated for 6 vowel counts. This applies to Madd Laazim (مد لازم). Example: الضالّين

Orange-Red — Obligatory Prolongation (Madd Wajib Muttasil)

The orange-red color marks obligatory prolongation of 4 to 5 vowel counts. This occurs when a Madd letter is followed by a Hamzah in the same word (مد واجب متصل). Example: سماء

Light Orange — Permissible Prolongation (Madd 'Aarid Li-Sukoon)

The light orange color marks elongations permissible at 2, 4, or 6 vowel counts. This typically occurs at the end of a verse when stopping (مد عارض للسكون). Example: العالمين when pausing at the end.

Yellow — Normal Prolongation (Madd Tabee'i)

The yellow color indicates the natural prolongation of 2 vowel counts that applies to standard Madd letters (مد طبيعي). Example: قال

Green — Nasalization (Ghunna)

The green color highlights ن (Noon) and م (Meem) when they carry a nasal sound. The resonance comes from the nose and lasts 2 vowel counts. Example: من نعمة

Light Blue — Echoing Sound (Qalqalah)

The light blue color identifies the five Qalqalah letters — ق ط ب ج د — when they appear with a Sukoon. These letters produce a slight bouncing or echoing sound, especially when stopping at the end of a verse. Example: أحد

Dark Blue — Emphatic Pronunciation (Tafkhim)

The dark blue color highlights letters pronounced with a heavy, full sound. This includes ر (Ra') with Tafkhim, and all letters of Isti'laa (elevation): خ ص ض غ ط ق ظ. Examples: الحرام، خالدين، الصالحات

Grey — Silent Letters

The grey color marks letters that are written but not pronounced during recitation. Example: the أ (Alif) in الله after إلا, as in لا إله إلا الله

Note: The Tajweed colors in Tarteel cover Madd types, Ghunna, Qalqalah, Tafkhim, and silent letters. Rules such as Izhar, Idgham, and Ikhfa' are not currently part of the color-coding system.

What is the difference between Tajweed colors and mistake highlight colors?

They are two completely separate systems. Tajweed colors are fixed — every user sees the same colors on the same letters, because the colors mark pronunciation rules that are part of the Quran text itself. Mistake highlight colors are personal — they change based on your own recitation history and show where you have been making errors. Learn more: Understanding mistake highlight colors
